new and useful luilniicatin Device, oi? which the following; is a specification.

This invention has tor its object a lubricatinp,- device which. is rnirticularly simple and economical in construction and highly efficient and durable in use, and turther which can be readily applied to bearings haying pasta/nee ot' dittoront depths tor reoil cups and ClQ'i MQS ceivinp; the stems oi wrthout adrustinn'.

lit further? has for its object a Filtklllj teed tor lubricating devices having}; rolling; delivery members. v i

The invention consists in the novel tea turea and in the combinations and construc-' tions hereinafter set forth and claimed.

In describing: this invention reference is had to the accompanying drawin in which lilre characters desig ate corresponding parts in all the views.

Figure 1 is a Vertical sectional View of one embodiment ott this lulnricaton. the bearinn; and the shaft iournaled in the hearing; be inn also shown in section.

Figure 2 is a iira o inentary View similar to Fig". l on a slightly enlarged scale, oi another term of my inventionl Figure 5% isn view similar to l in'. In at a th rd term oi? adaptation ot this invention This invention comprises primaril a lubricator located atthe hiner end ot a trans- "verse passage in the bearing" block an d coinnrisino: a head or body slidably ii tino' the passage and termed with throunh and with the reta ner Fo the rol ino' delivery member an inwa dl e ten dine: tubular stem alined with said hole it also comprises a lubr cant snnnly lement haw inn a portion ertendine' into the outer end oi the passan'e in thobea ne and s aced apart trorn the lnbrieator so that the lub ieator may he placed into the peasant oi th hearinm and the supply element which is usually a cup havino: a stem hichean he se cured into the outer end oi such nassao e regardless oi the depth oi the passi, ye in the hearing. t

This lnln'icatin dev ce also ooinini'ises a particularly simple and e'liieiont sio'ht teed tor lubrieati' m? devic s having rollinn" dolivery nietnbe an balla h ole th ere a 1 designates the bearing; 2 the shaft journ aled m. the bearing; and 3 the usual bushing between the shatt and the bearlng. 4. 1s

] the transverse passage termed in the hearing", and 5 is a passage termed with a bushmg and almed with the passage 4; and being usually oi less diameter than the passage t.

6 the lubricator which comprises a body, or head slidably mounted in the inner end oil the paseage 4: and having a pas 'age therethrough and also a tubular stem 7 projecting from itsinner end through the passage 5 in the bushing); 8 is a rolling deli very menu her at the inner end oi" the tube 7. The end margin of the tube 7 is turned inwardly into a circle of less diameter than the ball so that the ball is held from displacement out oi the tube. The tube 7 as here shown, is inserted in the passage of the head 6 and the ball is retained in the passage by a retaining member having; a passage therethrough, it being here shown as a hollow plug; 9 threading into the outer end of the tube 7.

The lubricant supply element may be a tank communicating; with a pipe or any other means with the 4-, and as here shown, this supply element is an oil cup 10 havinga stem 11 extending" into the onterend of the passage 4L, it being here shown as threading; into the outer end of such passage 4-. Th s oil cup may be oi any suitable form, size and construction and as l'1ereshow1n includes upper and lower heads 12" held together i by a tube 13 threading into the lower head 12" at the upper end of the stem 11, the upper head 19, threading on the upper end ot the tube, and a cylindrical glass wall l t interposed between the heads.

Also, a cap or closure 15 threads on the upper end of the tube. The tube is proyided with suitable openings 16 into the interior oi? the cup. l-lowever this oil supply member may be of any suitable form, size and construction.

The sight teed means by which it can be determined whether or not the oil is be inn; delivered by the member 5, comprises a rod 17 having a head 18 resting on the delivery member 8 the rod extending upwardly tlwough the tubular retaining lnemher 9 of the lubrioator 6 and into the stem 11 centrally thereof and the stem '11 is riot-med with a sight opening: or Window 19.

ant laes tube l9 ie held. in the portion may be eliminated and in order that the of thestemll formed with a sight opening in order toclose such opening, this tube being held in a position by an externally threaded ring threading in the lower end of the stem 11 against a suitable packing and the delivery member 8 against the shaft 2.

In operation, the lubricator 6 is dropped 7 into the passage 4 of the bearing and the 7, cup 10 threaded into the upper end of the passage 4. When there is oil in the cup and the shaft is'running, the oil is drawn into the passage 4 from the cup to the stem 11 through the passage of the retaining memher to the delivery'member 8 and as the cupis practically airtight, air seeps inwardly from the bearing and passes in bubblesup. along the rod 4: past the sight open- .ing "so that it can be quickly determined whether or not oil is being fed. lVhen desired, the lubricator can be removed after he cup 10 is removed .bypulling on the 'As seen in Fig. 2, the sight feed feature lubricator 6 may be removed it is provided with a suitable yoke 24 or other means by means of which a rod having a hook at its end may be hooked under the yoke 24. Also,

, the tube of the lubricator above the delivery ball inaybefilled with one or more balls 25.

seen in Fig. 3, the outer end of the passage 4 may be closed by a closure or plug 25 andthe passage in the bearing filled with oil to serve as an oil reservoir.

f This'lubricator and lubricating device is particularly advantageous in that it is economical'in construction, and can be made standard to all bear ngs without prov ding an adjustable stem, and further in that it ei emefiis ly r si se 0 the d p of t eie sas tfll ar n W ho ny tent1on,"calculation or adjustment by the operator.

a rod resting at its lower end on the delivery member and extending upwardly through the passage, a lubricant cup having a'stem extending into the outer end of said passage, the stem being formed with asight opening and a rod extending through the portion of the stem formed with the sight opening, substantially as and for the purpose set forth.

6. The combination of a bearing and a being formed with a trmisverse passage Shaft journaied in the bearing, the beari therein opening into the bore of the bearing, of a lubricating d eviee including a delivery member arranged in the passage and engaging the shaft, an oil supply including a portion extending into said passage and formed with a sight opening, a rod engaging the delivery member at its inner end, the rod extending through said portion, substantially as and for the purpose described.

7. A lubricating device comprising a rotary delivery ineniber said device being; int-med with a sight opening at a point re mote from the delivery member, and ineane ior eondmting air entering at the deiivery end thereot across the sight opening, eubstantiaiiy and for the purpose specified In testimony whereof, I have hereunto signed my name at Syracuse, in the county oi Onondaga, and State of New York, this 22nd day of May, 1922.
